Most homeowners benefit from the security provided by burglar alarms like the Intermatic SP230 wireless alarm. The SP230 wireless alarm features a motion sensor which sounds when the alarm is armed, as well as a "radio frequency" controlled siren speaker unit which must be programmed. Leave the alarm freestanding or mount the unit next to your front or back entrance. Programming the wireless alarm system requires setting the switches and selecting the security code. You can complete the setup in less than an hour. Use the Status LED indicator to verify that the alarm is armed or disarmed.
